The main objective of this study was to estimate the confidence intervals of population mean by bootstrap.Utilizing four bootstrap ways and common way to estimate the confidence intervals of population mean,and using R to carry out the estimation.The estimated lengths of confidence intervals by bootstrap were less than the common way.The results show the method of bootstrap can make the confidence coefficient more precise than the common way.
